The Unexpected Gateway

Kevin Charles Redmon points to new research indicating that “marijuana may be a ‘gateway drug’ to cigarettes”:

The recent [National Institute on Drug Abuse] study is important because it demonstrates that, even if THC doesn’t promote a neurochemical gateway for heroin and cocaine addiction, it does for nicotine.

The popularity of e-cigs may be changing that. And newly popular vaporizers to inhale THC act similarly: call them e-joints.
